Fire Sprinkler Maintenance

Under normal circumstances, your residential fire sprinkler system will require minimal maintenance, with exception of the following:

1. On a regular basis, observe the system’s water pressure on the fire sprinkler riser gauge.  If the gauge reads zero, contact a licensed fire sprinkler contractor for an inspection.


2. On a yearly basis, open the system test valve (Labeled ‘Main Drain’) until the alarm bell begins to ring; a delay of 30 to 60 seconds is normal. You may see a drop in water pressure upon opening the valve. The pressure should stabilize for the 90 seconds it is left open. The stream should be steady and not choppy with air pockets after the initial opening. If the alarm fails to ring after this period, contact a licensed fire sprinkler contractor for an inspection.


3. Replace any sprinkler exhibiting corrosion or damage.


4. In the event that remodeling or construction has altered the original configuration, additional fire sprinklers should be installed, as required, to maintain protection level.

Good Practices 

  • DO NOT HANG anything on fire sprinklers or pipes.

  • PROTECT FIRE SPRINKLERS FROM BUMPS. Be careful when carrying ladders and other large or tall items. 

  • DO NOT PAINT the fire sprinkler or the cover. 

  • DO NOT BLOCK your fire sprinklers. Keep pictures and large/tall furniture away from sprinklers on the walls. Hang lamps and plants away from fire sprinklers.

  • CONSIDER LOCATION OF PIPES BEHIND THE WALL. Avoid using nails or screws to hang pictures on the wall near the sprinkler pipe.
